IMPROVEMENT IN LIFT-PUMPS.

Specification forming part of Letters Patent No. 178,624, dated J 1111613, 1876 application filed April 11, 1876.

To all whom it may concern:

Be it known that I, CHRISTIAN Fox, of Gap, Salisbury township, Lancastercounty, in the State of Pennsylvania, have invented certain Improvementsin Preventing the Freezin g of Lifting-Pumps, of which the following isa specification:

The object of this invention is to apply a simple and efficientarrangement to prevent the splitting or damage of frost in woodenlifting-pumps during winter, as well as to draw 011 the warm waterstanding in the stock during summer.

The accompanying drawing, with the letters of reference marked thereon,and a brief explanation, will enable those skilled in the art to makeand apply this device, in which- A is to represent one of the common orencumber pumps now in common use through the country; B, the pump-bed;P, the spout. The device consists in the combined spout and leveredvalve, attached below the frostline to one side of the pump, bored toopen through the attached spout L, covered by a valve, M, connected withan arm, J, and held by a pivot-bolt in a pair of brackets attached tothe base-plate H, with which the spout is also cast in one piece. Thevalve is provided with stuffing, as also the plate, to prevent leaking.Said valve is held firmly closed by a coiled spring, K, connecting theend of the lever J with the spout L. In order to open the valve atpleasure, a wire, E, is attached to said valve lever J at I, and carriedup through an opening, 0, in the pump-bed, held by a keeper, I), and theupper end attached to a headed pin, f, on an eccentric lever, F, actingupon a fulcrum-plate, G, affixed to the pump-stock at a convenientheight vertically over the lowerdevice.

The operation is easily understood. By-

turning the eccentric lever F the wire-connection with the lever J opensthe valve M, with which the lever is connected, and the Water above thespout L is discharged, and preventin winter, and equally desirable inthe hot season during summer. Instead of pumping off the warm water inthe upper part of the stock, it is readily drawn off. i

The eccentric lever, as well as the valvelever and supports, is easilycast and galvanized, and put on sale as anew article to the trade, whichwill evidently findfavor by all who use wooden lifting-pumps, so commonin the country.

I am aware that several arrangements have been made with the same objectin view, as in Patents No. 174,688 and No. 174,725, both dated March 14,1876, which are operated by a rod or connected with the pump-handle. Thevalve is also connected to a straight lever, operating against the outerend of the spout, variously inserted into the pump-stock; but my valveacts direct upon the seat in the bracket-plate, and has a right-angledleverconnection over a spout, (or, rather, tr0ugh,)

closed-above only in front. Therefore What I claim as my invention is-The combination of the cam-lever F, fulcrum-plate G, and wire E,attached to a horizontal lever-arm, J, having a vertical valve,

M, attached, to set againstthe opening in a supportingbracket, H, whichalso supports an open spout, L, closed above'only in front, the wholearranged and operated substantially as herein shown and set forth.
